Answer:
Periodic phenomena means that the phenomena has a (almost) constant time period or space period.
As you know, the trigonometric functions cos(x) and sin(x) also have a constant period of 2*pi, so these functions are really useful to model periodic phenomena.
Now, the problem may be that the trigonometric functions may be useful to describe the "periodic" part, but not to describe the actual phenomena.
An example of this can be a square alternating current.
While it has a constant period like a trigonometric function, the trigonometric functions can not really model the "square" part of this current (you know that the sinusoidal functions actually are curves and continuous)
Here comes something called the Fourier Series, that are series of the form:
F(x) = a₀ + ∑(aₙ*cos(nx) + bₙ*sin(nx))
That can be used to model almost any periodic phenomena, but the actual Fourier Series may be hard to construct.
<u><em>Answer:</em></u>
Fraction of the whole band playing snare drum = 
of the whole band
<u><em>Explanation:</em></u>
<u>We are given that:</u>
Fraction of percussionists = 
of the whole band
Fraction of those playing snare drums = 
the percussionists
Now, to get the fraction of the whole band playing snare drums, we will need to multiply the fraction of percussionists by the fraction of percussionists playing snare drums
<u>This is done as follows:</u>
Fraction of the whole band playing snare drum = of the whole band

Answer:
J---
Step-by-step explanation:
If she made 1 Dozen (12) and he kids ate 3, (12-3= 9), she needs to make how many more cupcakes, and since we can use a variable, c + 9 = 24 (Because she promised to bring 24------She would need to make 15 more cupcakes)
The selling price would be $87.50 originally!
I hope this helped! Mark me Brainliest! :) -Raven❤️
